AUSTRIA-HUNGARY.

To all whom it'may concern:

Be it known that I, Broom Knixonn, a subject of the Emperor of Austria-Hungary, residing at Gumpoldskirchen, near Vienna, ArstriaHungary, have invented certain new and useful Improvements in Rotary Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The present invention relates to rotary machines'in which vanes or slides, guided in longitudinal slots of a rotary drum, are caused to slide to and fro in an axial direction by guide surfaces operating upontheir ends, and it relates more particularly to that construction of machines of this kind which is describe-din the U. S. Patent to Pittler No. 894391 dated July 28, 1908, having working chambers formed'by radial annular grooves in the rotary drum in which grooves engage stationary abutmentsfitted to the casing, the vanes or slides being provided with notches by which'they are enabled to clear the abutments. In known machines'of this .kindthe vanes are guided by cam surfaces. It follows therefore that the end faces of the vanes and the guiding surfaces touch each other on lines only, thus producing unfavorable conditions of surface pressure and wear.

' According to the present 'inventlon the controlling device comprises inclined-plane surfaces which abut against sliding blocks or shoes having plane sliding surfaces and connected with the ends of the varies by means of universal joints, so that the said sliding shoes, whatever position they may occupy during the revolution of the drum, are able to adjust themselves accurately to the inclined surfaces. By this means, uniform distribution of pressures over the whole face of the sliding blocks is attained and consequently excessive pressures per surface unit are obviated.

In the drawing Figure 1 represents a constructional form of the invention in horizontal longitudinal section. Fig. 2 is a cross section along line 2-2 of Fig. 1, the outer casing being omitted. Figs. 3 and 3 show modifications of details.

The ma chine shown in Figs. 1 and 2 comprises a. drum a mounted on a shaft 7) and provided with longitudmal slots 0 and anemrtnisamcn 'nnAn 'vxaam,

nulargroovesd. Abutnients a, mounted in known manner on the casing Z, engage with the annular grooves (Z. In the longitudinal slotsc. vanes e are guided, provided with notches f, which allow them to clear the abut'ments extending :into the annular grooves (Z. .The vanes e, at their ends'are provided with pins 9, upon which are mounted balls h. Thelatterare lodgedin hemispherical recesses of the sliding shoes-i. it the inner faces of the covers ofthe caslng inclined planes m are formed. The covers are mounted in such a position on the casing Z that their inclined planes mare parallel to each other. On-these-latterthe sliding shoes iglide with their likewise plane sliding surfaces, The sliding shoes 2' may be'pressed overthe balls h. For this purpose they are preferably not ,made' of metal, but are produced with theaid of high pressure and heat from a composition of resinous and fibrous materials which does not swell'up in water.

In Fig. 3 the sliding shoeshave the shape of ring segments insteadof'being circular as-lllustrated in Fig. 2-; theymayhowever have any other suitable shape.

The guide surfaces of the two covers may if, desired, be rendered exchangeable, as shown in Fig.4,so that they can be.produced from a metal which is suitable lto work together with the material of the slidlng shoes. An alloy of iron and nickel has proved to give particularly satisfactory regroove, a slide axially movable in said longitudinal slot and having a notch corresponding to said circumferential groove, parallel inclined plane surfaces in said casing opposite the ends of said rotary drum and sliding shoes directly articulated to the ends of the slide by means of ball joints and having plane sliding surfaces in contact with said inclined surfaces.

parallel inclined plane surfaces in said cas- I in opposite the ends of said rotary drum, sliding shoes in contact With, said inclined surfaces, ball sockets therein, balls lodged in said socket-s having recesses, and pins on the ends of said slide engaging in said recesses.

3. In a rotary machine the combination of a casing, a rotary drum therein having a circumferential. groove and a radial longitudinal slot, an abutment fitted to said casing and engaging into said circumferential groove, a slide axially movable insaid longitudinal slot and having a notch corresponding to said circumferential groove, parallel inclined plane surfaces in said casing opposite the ends of said rotary drum, sliding shoes in contact With said inclined surfaces, ball sockets in said sliding shoes, and balls arranged at the ends of said slide and lodged in said ball sockets, said sliding shoes consisting of a material adapted to be pressed over said balls. 7

4:. In a rotary machine the combination of a casing, a rotary drum therein having a circumferential groove and a radial longitudinal slot, an abutment fitted to said casing and engaging into said circumferential groove, a slide axially movable in said 1ongitudinal slot and having a notch corresponding to said circumferential groove, parallel inclined plane surfaces in said casing opposite the ends of said rotary drum, sliding shoes in contact with said inclined Copies of this patent may be obtained for surfaces, ball sockets in. said sliding shoes, and balls arranged at the ends of said slide and lodged in said ball sockets, said sliding shoes consisting ofa composition of resinous and fibrous materials.

5. In a rotary machine, the combination of a casing, a rotary drum thereinlhaving a 1 circumferential groove and a plurality of radial longitudinal slots, an abutment fitted to said casing and engagingintosaid cirumferential groove, slides axially movable in said longitudinalslots, each of which slides has a notch corresponding to said circumferential groove, parallel. inclined plane surfaces in said casing opposite the ends of engaging into said circumferential grooves,

slides axially movable in said longitudinal slots and having notches correspondingto said circumferential grooves, parallel inclined plane surfaces'in said casing opposite the ends of said drum, and sliding shoes directly articulated tothe ends of the slides by means of ball joints and having, plane surfaces sliding in contact with said inclined surfaces.

In testimony whereof, I afiiX my signa ture, in presence of two Witnesses.
